Lub hauv paus ntsiab lus ua haujlwm ntawm tag nrho AC generator

Thaum lub excitation winding yog energized los ntawm cov hluav taws xob txhuam nyob rau hauv lub sab nraud Circuit Court, ib tug magnetic teb yog generated, ua rau lub claw ncej yuav magnetized rau N thiab S ncej. Thaum lub rotor tig, cov sib nqus flux hloov pauv hauv stator winding. Raws li lub hauv paus ntsiab lus ntawm electromagnetic induction, alternating induced electromotive quab yuam yog generated nyob rau hauv peb -theem winding ntawm lub stator. Qhov no yog lub hauv paus ntsiab lus tsim hluav taws xob ntawm AC generator.
Lub synchronous generator rotor nrog DC excitation yog tsav los ntawm lub prime mover (ie cav) tig ntawm ib tug ceev ntawm n (rpm), thiab peb -theem stator winding induces AC peev xwm. Yog hais tias lub stator winding txuas nrog ib qho hluav taws xob load, lub cev muaj zog yuav muaj AC lub zog tso zis, uas yuav hloov mus rau DC lub zog los ntawm tus choj rectifier hauv lub tshuab hluav taws xob thiab cov zis tawm los ntawm cov zis tawm.
Lub tshuab hluav taws xob AC tau muab faib ua ob ntu: stator winding thiab rotor winding. Peb -theem stator winding yog faib rau ntawm lub tsev raws li lub kaum sab xis hluav taws xob sib txawv ntawm 120 degrees ntawm ib leeg, thiab lub rotor winding yog tsim los ntawm ob tug ncej claws. Thaum lub rotor winding yog zoo siab los ntawm cov tam sim no ncaj qha, ob tug ncej claws tsim N thiab S ncej. Cov kab hluav taws xob sib nqus pib los ntawm N ncej, nkag mus rau hauv stator core los ntawm qhov sib txawv ntawm huab cua, thiab tom qab ntawd rov qab mus rau tus ncej S uas nyob ib sab. Thaum lub rotor tig, lub rotor winding yuav txiav cov kab sib nqus, tsim cov sine electromotive quab yuam nrog qhov sib txawv ntawm 120 degrees ntawm hluav taws xob℃lub kaum sab xis nyob rau hauv stator winding, uas yog, peb -theem AC zog, uas yog tom qab ntawd hloov mus rau hauv DC fais fab tso zis los ntawm rectifier Cheebtsam ntawm diodes.
Thaum lub kaw lus kaw, lub roj teeb ua ntej muab tam sim no. Circuit Court yog:
Cov ncej zoo ntawm lub roj teeb → Lub teeb qhia lub teeb → Regulator contact → Excitation winding → Grounding → Negative pole of battery. Lub sijhawm no, lub teeb qhia kev them nyiaj yuav qhib vim qhov tam sim no dhau los ntawm nws.
Tab sis tom qab lub cav pib, raws li lub tshuab hluav taws xob ceev nce, lub davhlau ya nyob twg voltage ntawm lub tshuab hluav taws xob tseem nce ntxiv. Thaum cov zis hluav taws xob ntawm lub tshuab hluav taws xob sib npaug rau qhov hluav taws xob ntawm lub roj teeb, lub peev xwm ntawm "B" thiab "D" terminals ntawm lub tshuab hluav taws xob sib npaug. Lub sijhawm no, lub teeb qhia them lub teeb tawm vim qhov tsis muaj peev xwm sib txawv ntawm ob lub terminals. Qhia tias lub tshuab hluav taws xob ua haujlwm ib txwm ua thiab cov khoom siv hluav taws xob tau muab los ntawm lub tshuab hluav taws xob nws tus kheej. Peb -theem AC electromotive quab yuam tsim los ntawm peb-theem winding nyob rau hauv lub tshuab hluav taws xob yog rectified los ntawm diodes thiab outputs DC fais fab mov los muab lub hwj chim rau lub load thiab them lub roj teeb.
